AnrIonEE'PIne TIE PL TE; a e 7 Application filed December 15, 1922.Serial No.- 607,229,"

T all whom vit may concern." 7 Be it known that I, Bum H. PoULos,

citizen of the United States, residing at Haugan, in Mineral County andState of Montana, have invented certain. new; and

useful Improvements in Anticreeping Tie Plates, of which the followingis aspecifif cation.

My present invention relates to improve ments in anti-creeping tieplates designed to be used under the rails of railway tracks to preventlongitudinal creeping of the, rails, as well .as to prevent lateralmovement or spreading of the rails, when the latter are subjected to thestrains imparted thereto by the weight of passing rolling stock. I V

The primary object of the invention is the provision of a tie platewhich'is comparatively'inexpensive in cost of production, is simple inconstruction and durable, and

which is providedwith locking means for maintainin the rail in propercondition at,

all times. ue to its simplicity in construction the plate maywithfacility be installed in position for use beneath the rail and therelocked, and subsequently the plate may be maintained in proper positionfor holding the rail in safe condition. To this end the inventionconsists in certain novel combinations and arrangements withthe plate,which plate extends substantially from edge to edge of the rail base,whereby the plate and locking member or section afford a secure anchorfor the rail. In practice a suitable number of the. plates are anchoredto the ties and the plates are placed at desired intervals throughoutthe lengthof the rail.

In the accompanying drawings I have illustrated one complete example ofthe physical embodiment of my invention whereln the parts are combinedand arranged according to the best mode Ihave thus far devised for" thepractical application of the principles of my invention.

Figure 1 isa perspective view of a .porv

stood I have shown portion of a standard I track rail as 1 with itsflanges 2 and 3formdesignated as .y The tie platesj5 are anchoreddirectly on ing the base thereof, and the cross tiesare I l v 601 thecross ties and theseplates, which are 1 produced in suitablemanner, areof standard' sizes'to correspondwnlrthe rail flanges and base,fand areinstalled beneath the rail and on the tie at intervals throughout thelength of the rail to meet existing conditions.

The plate is approximatelythe width of the *railbase, extending fromedge 'to edge there f of, and, is fashioned with. a retaining flange 6to fit over one ofthe rail flangeslas 3, and

a lateral extension or spike flange 7 having one or more-spike holes 8.A

On the under faces of theplates" are prowhen the plate is slipped undertherail b se,

jecting spurs 9, and it will be apparent that as from the right side"in' Figure 2, thesei spurs will become embedded in the top face of thetie} By. means. of spikes idrive'n through the spike holes and into thecross tie and with the aid .of the spurs, the tie-plate is securelyfastened to the cross tie,-an d the retaining flange by itsengagementwith the rail flange 3 holds the rail from spreading.

At the edgefof the plate opposite to the; retaining flange 6, the-plateis fashioned with. a longitudinally extending tapered groove 10 in itsvupper surface, the outer wall of the groove being disposed at a slightangle to the longitudinal axis of the plate, and the inner, undercutwall 11 of the groove being disposed parallel with the longitudinal axisof the plate. At the edge 7 of the plate a corner rib 10 is thus formed,

which tapers in width from end to end, the

outer, top edge ofthe rib being parallel with the longitudinal axis ofthe plate.

In connection with the 'tieplate Iutilize a lockingsection 12,'locatedat the side of the rail and adapted to interlock with the plate inengagement with the rail, to maintain the flange 2 of the rail inposition. 1 The detachable and adjustable locking section conforms tothe shape and size of thetie plate and forms a complementary part 7thereof. It is provided with spike holes 13' through which the spikesare driven into the tie for holding the section in locked posiing'flange l4.- complementary to the flange .6, to engage over and hold thebase flang 2 of the rail.

, tion, and is fashioned with a'flange retaing.

A locking rib 15, in the shape or" a Wedge, is providedfat the undersideof the retaining flange 14, and between the rib and flange 14 a groove16 is fashioned, said groove ex tending laterally over the flange. Asecond groove 15' which extenos vertically, is pro vided in the underportion or" the locking section, and the inner face of the crib 15 isbeveled as seen at 17.

7 After the tie plate has been installed under 'the'rail with theretaining flange engaged over the rail flange, the locking section maybe fitted and adjusted and secured in locked position. In locatingthe-locking section,.it may first be held between the ties with theWedge rib l5 alined with the m tapered groove 10, and While in thisplane the Wedge is inserted intothe groove. The retaining flangeWhilethesection is in this position projects over the edge of the railflange 2.' The section inaynow be forced or moved along the edge of therail flange and due to the angular'disposition of the outer Wall of thegroove 10 the vertical wall of the slot 16 of the locking section iscaused to frictionally engage the edge of the flange, Whiletheretainingffiangev-l lis forced over the railfiangeQ. In this manner thetwo rail flanges 2 and am clamped securely between the respectiveretainingfianges 1% and 6, and with the spikes driven through theseveral: spike holes 8 and 13- a'nd spurs '9' embedded in the crosstie,the rail is firmly anchored by the tie plate. to the cross tie. Inthe event thatzthenecessity should arise for tightening the lockingmember, its spikes may be removechand then the section may be drivenlongitudinally of the tie plate, causing the section to be broughtnearer to the rail for clamping action. In case it is necessary toremove the tie plate, after the spikes have been Withdrawn, the lockingsection may be backed off the tie plate, thus, permitting the plate andI locking section to be removed fronropposite sides of the rail.

Having thus fully described my invention, hat I claim-asneW -and desireto secure by LettersPatent is v 1 1 1 The COlllbl ation with tie'platehaving a rail retaining flange extending throughout its length, aperforated spike flange andtieengaging means on its bottom, of a lockingsectionhaving a rail retaining flangeextending: ovr said plate andhaving its bottom flush With the bOttGlYl'Ol the plate andperforated'for spikes, said locking section having a wedge shapedbead'ivith a beveled face, and said tie plate having a top groove formedwith an undercut-Wall parallel with the longitudinal axis of the plateand a perpendicular Wall disposed at an angle to the longitudinal axisof the tie plate.
